Interesting, flipping Bach's Prelude in C Minor gives it a more major sound.
Also inversion is a fairly common technique in writing developments so some fugues will sound quite similar.
- TheOtherHobbes 10y agoThe official way to invert intervals is to subtract the range from 9 (3rd becomes 6th, 2nd becomes 7th, etc) and flip the character (major <=> minor, aug <=> dim, octaves and unisons don't change.) The range is defined by the relationship to the key root, so you need to know the key to do this properly. You can invert at other intervals, which creates inversion plus transposition.
